Thanks. [he's relieved to hear that-- even though he really didn't expect any different. Korra knew him better than that-- at least, he hoped she did.]

I don't think there's any harm in telling him that, and giving him the truce. At least, I can't think of any reason not to. It's not like he doesn't get what's coming to him back home. [aka, that's not their fight, and as long as he behaves himself, Mako could care less]
